SPEGIFICATION forming part of Letters Patent No. 710,474, dated October 7, 1902.

Application filed January 16,1902. Serial No. 90,021; (No model.)

To (L7/Z 7071/0711/ t ntf/,y concern:

Be it known that 1, IGNACIO LZAGA, a citizen of Cuba, residing.r in the city of Havana, Cuba, have invented a new and useful Improved Packing-Machine Designed 'for Enveloping Small Articles, such as Cigarettes, Cakes of Soap, Cards, Bonbons, dac., ot which the following is a specitication.

The accompanying drawings illustrate the invention, of which- Figure l is an upright side View of the machinewith the frame in section; Fig. 2, atop or plan view of the same; Fig. 3, a top or plan view of the apparatus with the receptacle for the article to be wrapped and the wrapperfeeding devices removed and having a part of the table broken away to show the mechanism below. Fig. 4 is an enlarged view, in vertical section, of part of the machine from the receptacle to the drum for discharging the articles when wrapped; Fig. 5, a top view of the folding device, partly broken away; Fig. (l, a view ot" the attachment to the plunger, used with wrappers of stiff paper or cardboard; Fig. 7, a sectional view of the receptacle used for cigarettes with the hopper and devices for reciprocating` the same; Fig. 8, a view of the lower part of the receptacle for cigatettes, showing the plunger and chain for removing dust or scraps therefrom; Fig. 9, an end view of the compressor with the compressing devices above and at the sides of the cigarettes and the guiding devices for the wrapper; Fig. 10, a front view ofthe pasting device. Figs. 1l to 17, inclusive,showthe successive forms taken by the wrapper in the operation of folding it abontthe article.

lVhile the devices and their operation will be herein explained in connection with wrapping cigarettes in packages, it will be understood that other articles may be packed and wrapped in this apparatus, as mentioned above. o

1 is the frame of the apparatus, upon which is mounted the reciprocating` plunger 2.

3 is a shaft running longitudinally beneath the table.

4 is a bracket mounted on the end ofthe table, in whichis journaled the shaft, which carries the gear-wheel l5, which meshes with the gear-wheel 7, mounted on the shaft 3, whereby motion is im parted thereto by means ofthe driving-pulley S. A bevel-wheel 9, Fig. 3, meshing with the wheel l0, gives a revolving motion to the crank ll. This crank is provided witha pin l2. An upright lever 13 is pivoted at its lower end to a crosspiece 14, attached to a suitable part of the frame, and is provided with the s101315, within which the crank-pin 12 works and imparts a forwardand-backward movement to the lever. A link 16 connects the upper end of this lever with the plunger and imparts thereto a reciprocating movement.

Seated upon the frame is a box 17, Figs. 1, 4, and 7, constructed as shown in Fig. 7. It is provided with a series of partitions 18. These partitions are stationary and are inclined so that the spaces between them are wider at the top than at the bottom to permit an easy access of the cigarettes which fall into them from the hopper and rest upon the plate 19 at the bottom of the box. Above the receiving-box is the vibrating hopper 20. Upon the shaft 3 is mounted the wheel 2l, and from this wheel a belt 22 extends around the wheel 23, which carries a pin 24, to which is pivoted one end of a link 25, whose other end is pivoted to the frame of the hopper 2O at 2G to thereby vibrate the hopper as the wheel 23 revolves and shake up the cigarettes therein and feed them int-o the box between the partitions. .The plunger 2 is constructed to cooperate with this box. Viewing Fig. 7, the plunger is shown in cross-sections located just beneath the bottom plate 1f). It is narrower in width than the plate and is provided with the overhanging piece 27, Figs. 1 and 2. This piece is arranged to leave the space 2S between it and the body of the plunger and is slotted, as shown at 29. This construction enables the overhanging piece to pass above the plate 19 to force the cigarettes from the compartments and the body of the plunger to pass below the plate to receive the cigarettes when forced out. The overhanging piece is wider than the plunger, so that its forks may enter allot' the spaces between the partitions in the box and force out their contents.

Mounted on the frame just in front. of the receiving-box is the compressor 30, Figs. 1, 2, 4, and i), constructed with the side walls 3l.

On the right in Fig. 9 is shown an open space 32, which serves the double purpose of forming a guideway for 4the side plunger 33, and the base of the channel forms a platform 34 to receive the cigarettes forced out of the receiving-boX byjthat part of the overhanging piece which extends beyond the side edge of v the plunger 2, and as the surface of the plunger projectingbeyond the receiving-box lies in a plane with the platform 34 of the box the rows of cigarettes when ejected will be partly on the surface of the plunger and partly on the platform. When in this position, the side plunger moves forward. This plunger and its operating mechanism are constructed as follows: Upon the shaft 3 is placed the cam 35 and suitably pivoted to the frame the lever 36, lo which is imparted a vibrating movement by the cam. At its upper end the lever is furnished with a piu 37. This pin forces the plunger forward against the tension of a spring 3S, Fig. 7. By this movementl the cigarettes are forced ofI" of the platform 34 and compressed together, so that they all lie on the surface of the plunger. At the proper time when the lever is withdrawn the spring 38 forces the plunger back. While the cigarettes lie in this position, held upon the body of the plunger 2 by the plunger 33, another operation takes place, that of compressing the cigarettes vertically, and this is accomplished by the following devices: An eccentric wheel 39, Fig. l, mounted on the shaft 3, imparts a vertical reciprocating movement to the rod or bar 40. (See Fig. 9.) This rod or bar has an arm 41 extending from its upper end and bent downwardly,terminatingin a plate 42, located between the walls of the compressor above the rows of cigarettes. A rod or b ar 43, mounted in brackets attached to the'frame so as to slide vertically, is retained in its upward position by a spring 44 and in' its downward position by the end of a lever 45, Figs. l, 2, and 9, which enters a slot in the bar and is retained there by a spring 46. A plate 47, attached to the arm 41 and moving` therewith, projects over the top of the bar 43 and forces it down. Projecting from the rod 43 is a roller 48, located beneath the cigarettes, which cooperates with the plate 42, and when the bar 43 is releasd the rod dies up, impelled by the spring 44. This roller rises with it, engages the cigarettes, and holds them between it and the plate 42. The lever 45 is suitably pivoted in the frame, as shown in dotted lines, Fig. 2, at 49. The arm of the lever extending beyond the fulcrum is provided with an inclined projection 50, which contacts with a suitable projection from the plunger 2 and throws the lever out of the socket in the bar 43 and releases the bar. These devices are so arranged to time their movements with each other that when the cigarettes are forced out of the box and are dropped partly on the plunger and partly on the platform in the compressor the bar 43 is held by the lever 45, and the roller lies below the plungerl and out of its way. This occurs about the time the plunger is near the end of its forward stroke and is ready to begin its movement backward. The plunger 33 then comes forward and compresses the cigarettes from the side, placing them all upon lthe surface of the plunger 2. As the latter moves backward the cigarettes are arrested by the plate 19. When the forward end of the plunger is back far enough to discharge the cigarettes, the bar 43 is released and the roller 48 rises and holds the cigarettes between it and the plate 42, when this latter plate descends with the bar 43 until it is caught by the lever 45 and held in place, as shown in Fig. 9, with the cigarettes in position to be thrust forward by the forward end of the plunger against the wrapper and into the folding devices.

Between the compressor and the folder the wrappers are fed and dropped by gravity. Viewing Figs. 1 and 4, 51 is a box in which the wrappers 52 lie in sheets one upon the other. l/Vithin the box are two upright rods or bars 53, preferably round in cross-section, and each of the wrappers is provided with notches 54, which fit over the bars. The othe.'1 end of the wrapper is formed in proper shape for the lip of the package. Mounted upon the boX are the bracket-guides 55,with in which is placed the sliding rod 56. oted to a projection from the end of this rod is a bar 57, which carries on its end a spindle upon which is mounted a roller 58. The roller may be covered with rubberor other suitable material. A spring-pawl 59, coperating with a ratchet 60, Fig. 4, suitably mounted upon the rod 57, is arranged to prevent the roller from turning on its forward movement and allows it to turn in its backward movement. Thus in its forward movementits friction upon the top wrapper will disengage the notches 54 from the rods 53, which hold it, without affecting the others. The movement of the parts is efected by a lever 61, suitably pivoted to the frame, connected at its upper end to the sliding bar 56 by the link 62 and at its lower end to the lever 13 by the link 63. Vhen a wrapper is pushed forward, it falls in the passage-way formed by the curved walls 64 and between the guide-plates 65. Below the frame of the machine the guides are extended by the tubes 66, Figs. 1, 4, and 9. These tubes are slotted and tted with a sliding piece 67, provided with a thumb-screw 68, by means of which the sliding piece is secured when properly adjusted. These sliding pieces are provided with the pins 69, Fig. 4, which stand in the path of the falling wrapper, arrest it, and hold it in position in front of the cigarettes ready to be forced against the wrapper and impel it through the folder 70. The guideplates 65 are secured to the curved walls 64 and project into the open space between them, Fig. 2. The lip of the wrapper as it descends strikes against the outer one, At a by which it is directed and guided.

Piv-

IIO

point near the table of the machine these plates are bent inwardly and form a narrow channel 71, Fig. 3, through which the wrapper passes in its descent. As the wrapper enters the mouth of the folder (see Fig. 4) it doubles over the cigarettes in the form shown in Fig. 11. Just inside of the folder are located the pieces 72, which fold in the corners of the wrapper. Beyond these pieces are the iianges 73, which fold down the upper margins of the wrapper, as shown in Fig. 13. The lower margins then contactwith the inclined planes 74,npon which theyride,and are forced up against the paste-wheel. Beyond these planes are placed the pieces 75, which fold the lower margins over the upper ones, as shown in Fig. 4. ln the rear of the foldingbox are located the spring-pins 76, Fig. 5, which ride along the side of the package until they reach a point beyond the ends of the cigarettes, when these pins act to force in the corners of the wrapper adjoining the lip, as shown in Fig. 15.

The pasting devices are seated directly over the folder. They are constructed and operate as follows: Figs. l, 4, and 10 show two upright walls 77, seated over the folder. These walls are secured to the frame and are provided with the journals supporting the paste-rollers. These rollers are marked 7S, 79, S0, and 8l, as shown in Fig. 4. At the other end are the cogged wheels S2, 83, 84, and 85, meshing with each other and receiving motion from the upright shaft S6, driven by the' beveled wheel 87, mounted on the shaft 3, operating through the bevel-wheels SS and 89. Running across the upper part of the frame is a rod 90, provided with the pendent plate 91, which drops down between the rollers 78 79, and in the angles formed thereby on either side a suitable paste is deposited, which the friction of the plate prevents from dripping and regulates the quantity of the paste distributed on the rollers. The rollers 80 S1 receive paste from 7S 79 by contact. The rollers 80 impart the paste to the lower margins of the wrapper when these margins ride upon the inclined planes 74, which bring them in contact with these wheels. Whenthewrapperpassesthefolder, it inters into the box 92. rlhis box is constructed with its interior about the size of the package and is open at both ends and receives its rotary movement from an upright shaft 93, driven by the bevelwheel 94 on the shaft 3, meshing with the wheel 95 on the end of the shaft, Fig. 4. At the upper end of the shaft, Figs. 2 and 3, is secured the beveled cogged wheel 9G, meshing with one, 97,011 the shaft of the box. The cogs of these wheels do not occupy the entire circumference, but are cut out in order to allow the shaft 93 to revolve without turning the box as long as the wheels present open faces to each other and turn the box only when the driving-@ogs mesh with those on the wheels of the box-shaft. This gives an intermittent movement t0 the box, allowing it to stand with one of its open ends presented to and in line with the package issuing from the folder, and when forced into the box remains there with its lip protruding from the end of the box in the form shown in Fig. 15. The box is then ready to be turned end for end by the intermittent movement above described. Projecting from the upper ends of this box, as shown in Fig. 4, are the curved plates 98. The wheel S1 of the pasting device being charged with paste is so placed that these curved plates contact with it as they turn and receive therefrom a supply of paste on their outer surfaces. Another curved plate 99 is secured to the table and lies below the box, Fig. 4. As the box turns the projecting lip of the wrapper is doubled over, as shown in Fig. 16, its inside surface is brought in contact with the gummed face of the plate 98, and as lthe box turns the lip lies between the two plates 9S 99. Vhen the box has been turned end for end and its opening lies in line with the plunger, the package is ready to be forced out of the box by another package from the folding devices, impelled by the plunger, which takes its place in the rotating box.

A drum 100 stands in the front of the box 2 and has erected upon it the boxes 101, constructed in size and shape to receive the package from the box 92. A series of projections 120 are placed on the face near the periphery of the drum. When the box 92 is turned, it strikes one of these projections and gives the drum a short turn, sufficient `to bring one of the boxes directly in line with the package. As the plunger forces a new package into the box 92 the one already there is forced out and into the box 101 in the drum, and in entering, the projecting lip X of the package being already supplied with paste, is doubled over in the form shown in Fig. 17. The package is now complete. It sometimes occurs that the package is not driven in entirely, so that its outer end will remain flush with the outer end of the box. To remedy this, there is suitably secured to the frame a plate 102, which projects downwardly. The plate is slightly curved. Atits lower end it stands farther away from the periphery of the drum than at its upper end, so that a projecting package will be forced in the box by contact with this plate the drum turns. I have also erected upon the frame of the machine a cylinder or tube 103 and have provided it with a piston or plunger 104. This tube is slotted at 105, and through the slot projects a lug 106, connected with the piston 104. A rod or bar 107 connects this lug with the lever 13, thereby imparting a reciprocating movement to the piston, which at the proper time moves forward and forces the package in front of it, so that it projects on the inner side of' the box, as shown at 108, Fig. 1. The piston is withdrawn before another movement is given to the drum.

IIO

A trough 109 is provided with a projection 110, Fig. 1, which contains a journal through which is passed the end of the drum-shaft. Beyond the drum-shaft the trough is supported in its position by one end of a bar 111, whose other end is secured to the frame of the machine. The trough receives the packages as they are shoved out of the boxes 101, and as the drum rotates the projecting end of the package 10S lifts up the end of the package last deposited in the trough and makes room for itself to enter the box and push forward the packages in front of it. From the end of the trough the packages drop upon a table or in a basket for the purpose.

Suitably journaled in the frame of the receiving-box are the spindles which carry the grooved pulleys 115 116 117 118. Around these pulleys is placed a chain which sweeps across the plunger' 2 to clearit from dust and keep it clean. Viewing Figs. Ll and 7, there is shown the wheel 23, driven by belt 22. Upon this shaft is mounted the pulley 117, which moves the chain. The other pulleys are idlers.

Fig. 6 shows a structure used with the device when the wrapper is composed of cardboard or very stiff paper. The plunger 2 carries the pin 119, arranged to be vertically movable. A plate 120 on each side of the plunger is provided with the slot 121, running parallel with the plunger and bent down at its rear end. The pin 119 enters this slot at the part bent down and impels the plates forward. The package is held between the ends of the plates projecting beyond the plunger until the folding devices have turned the margins of wrapper upon the plates. At this point the pin 119 rides upon the inclined plate 122 into the horizontal part of the slot. The plunger then moves forward, while the plates remain stationary, and forces the package from the folder into the rotating box.
